Definitions

  • US 2017/0019894 A1 discloses a method for reducing latency of uplink transmissions.
  • a user equipment may transmit in uplink transmissions in contention access resource or in granted resources.
  • Other documents illustrating access to wireless resources are:
  • At least some steps of the communications at 14, 16, 17, and/or 18 may be performed, for example, according to LTE or NR standard and/or other radio access technologies, e.g. WiFi, Bluetooth, and so on, according to the example.
  • JRP physical resources may comprise spatial channels which are not pre-assigned to one UE.
  • a UE may access the JRP by transmitting data in UL using a JRP spatial channel.
  • JRP physical resources may comprise power levels (e.g., power level ranges) which are not pre-assigned to a particular UE.
  • a UE may access the JRP by transmitting data in UL at its power level.
  • the JRP definer 30 may define the configuration data on the basis of criteria at least in part involving the determination of incorrect data 36. If a UL data is not properly received by the central entity and/or BS (JRP definer), the latter may request a retransmission of some data.
  • Figs. 7 and 8 refer to rules for retransmitting data previously transmitted (either in JRP or in G) while shifting to JRP the data originally scheduled for G.
  • This delete-rewrite techniques may be performed by the processor 42, and/or by the communication controller 43, and/or by other hardware, according to the examples and the implementations.
  • system 120 may comprise a non-transitory memory unit 126 (e.g., implemented in a read-only memory, ROM, a flash, a firmware, etc.) comprising instructions 126a which, when executed by a processor (e.g., processor 122 and/or 42), may cause the processor to perform at least one of the methods and/or operations described above and/or to implement the functions of the devices, products and systems described above.
  • a processor e.g., processor 122 and/or 42

Claims (22)

  1. Benutzergerät, UE (24, 26, 28, 40), das zu Folgendem konfiguriert ist:
    Empfangen, von einer externen Vorrichtung (22, 26, 30), von Konfigurationsdaten eines gemeinsamen Ressourcenpools, JRP, für eine Kommunikation Uplink, UL, in physischen JRP-Ressourcen (52, 52a-52k, JRP1, JRP2), die mit anderen UEs geteilt werden;
    Übertragen von Daten (1b) in dem JRP und, wenn eine erneute Übertragung erforderlich ist, Verwenden einer bestimmten gewährten Ressource (G) zum erneuten Übertragen der Daten (1b*) nach Ablauf eines Rücksetz-Zeitgebers (T1),
    wobei das UE konfiguriert ist, um einen unterschiedlichen Rücksetz-Zeitgeber (T1) in Bezug auf die anderen UEs aufzuweisen, dadurch gekennzeichnet, dass das UE ferner konfiguriert ist, um den Rücksetz-Zeitgeber von der externen Vorrichtung mit einer Nichtbestätigungsnachricht, NACK, zu empfangen.
  2. UE nach Anspruch 1, wobei das UE konfiguriert ist, um andere physische JRP-Ressourcen als einige andere UEs aufzuweisen.
  3. UE nach einem der vorherigen Ansprüche, das konfiguriert ist, um, während es auf den Ablauf des Rücksetz-Zeitgebers wartet, Kommunikationen auf anderen zugewiesenen physischen Ressourcen auszuführen.
  4. UE nach einem der vorherigen Ansprüche, das konfiguriert ist, um im Fall eines Empfangs eines Stummschaltungssignals einen Zugriff auf den JRP für eine bestimmte Zeit zu verhindern.
  5. UE nach Anspruch 4, das konfiguriert ist, um im Fall eines Empfangs einer Reaktivierungssignalisierung neu zu starten, um auf den JRP zuzugreifen.
  6. UE nach einem der vorherigen Ansprüche, das ferner konfiguriert ist, um ein Listen-before-Talk, LBT, zu verwenden, um auf den JRP zuzugreifen.
  7. UE nach einem der vorherigen Ansprüche, das konfiguriert ist, um die Daten erneut zu senden, wenn es bestimmt, dass innerhalb eines Schwellenwerts keine Bestätigung erlangt wurde.
  8. UE nach einem der vorherigen Ansprüche, das konfiguriert ist, um die Daten erneut zu senden, wenn es von der externen Vorrichtung informiert wird, dass Daten falsch empfangen wurden und/oder wenn eine Nichtbestätigungsnachricht empfangen wird.
